My parking lights, dash lights, and sunroof all quit!!!

I went out to my car to get in it while it was storming(of course!) and it would not start. I finally tracked that problem to recieving no power at the coil. I ran a new power wire to the coil and she runs great. at the same time all of the back lights for the dash, the parking/running lights, and the sunroof quit working. The headlights had also quit but they have since started working again and I still have brake and turn lights but no parking. I have checked every fuse in the car and not a single one is bad. I don't seem to be able to find any relay that is bad either. Any ideas?

The solution is 2 fold:
1. Replace the filler cap on the overflow bottle, the genuine RR part works best;
2. Replace the 'O' Rings on the heater matrix under the dash. This last is quite a fiddly job, go to www.rangerovers.net for full details on how to do it. If you take the vehicle to a RR dealer they want to charge huge amounts of money because they replace the entire heater box not just the 'O' rings.
